Abstract

Recent developments in room-temperature phosphorescence (RTP) from biobased polymers have shown great promise in realizing sustainable RTP systems. Here, we introduce an efficient “top-down” method to achieve RTP biofibers using bamboo following partial delignification (B-fibers). The photophysical characterization combined with structural, surface, and chemical inquiries along with DFT calculations revealed the fundamental reasons for RTP, associated with the interactions between cellulose, hemicelluloses, and the residual lignin. Multiple emissive oxygen-containing clusters and aromatic chromophores in the B-fibers were shown to be RTP-active with a lifetime of 294.9 ms. The RTP emission of the B-fibers was found to be sensitive to temperature, excitation, and humidity. Moreover, when combined with a water-soluble fluorescent dye, red afterglow emission was demonstrated under the effect of energy transfer. Following these results, we synthesized functional luminescent materials (paper, films, textiles, and aerogels), proposed herein as practical, sustainable, and compostable choices for photoexcitation in the visible range.

期刊介绍： ACS Materials Letters is a journal that publishes high-quality and urgent papers at the forefront of fundamental and applied research in the field of materials science. It aims to bridge the gap between materials and other disciplines such as chemistry, engineering, and biology. The journal encourages multidisciplinary and innovative research that addresses global challenges. Papers submitted to ACS Materials Letters should clearly demonstrate the need for rapid disclosure of key results. The journal is interested in various areas including the design, synthesis, characterization, and evaluation of emerging materials, understanding the relationships between structure, property, and performance, as well as developing materials for applications in energy, environment, biomedical, electronics, and catalysis. The journal has a 2-year impact factor of 11.4 and is dedicated to publishing transformative materials research with fast processing times. The editors and staff of ACS Materials Letters actively participate in major scientific conferences and engage closely with readers and authors. The journal also maintains an active presence on social media to provide authors with greater visibility.
